Client.exe crash - whenever transitioning between 1st cavern to 2nd cavern

Just ran through two characters through Act 1 - to kill Merveil, of 3-4 characters I ran to Merveil today, the last 2 DID experience, client.exe crash upon attempting to switch from the 1st cavern to the 2nd cavern.

Since I was able to recreate this crash with 2 different characters I thought I'd post.
